Extensions- 30 Sep 2024
After quoting for a single storey side extension / single garage we ended up having at alter the plans to just replacing the roof of an old coal shed / brick shed with corragated roof. These plans then developed into adding a roof over the alley between the house and the small out brick shed. Luke and Jerry did a fantastic job. They've got a great attitude to work (and life in general!) Despite several snags along the way (weather, materials etc) they were resilient and got the job done to a fantastic standard. Luke stayed in touch during exceptionally poor weather to ensure we were happy with the work and had no snagging issues. I've since asked them to return for some other work and look forward to trusting them again. Thanks Juke 😎

Twelve Construction Ltd
Rating: 5 out of 5
Extension Builder in Henfield
We’re not your typical building company. Our story began when two pilots partnered with a highly experienced builder to take on property investment projects. After three years of working successfully together, we saw the value in combining the precision, attention to detail, and management skills of aviation with the builder’s incredible knowledge and hands-on expertise. That partnership became the foundation of our firm a team committed to delivering high-quality refurbishments, extensions, and home transformations with the same discipline and reliability we’ve built our careers on.

We bought a run down flat in Brighton that needed a full refurbishment and some structural work. With a large garden, the guys at twelve designed and built a beautiful garden office for us too which has been such a brilliant space. We were worried costs would spiral out of control, but they gave us a fixed price contract and it really didn’t budge. Couldn’t be happier with them and Sam’s communication during the build really helped us keep on top of things even though we were not living in the area during the refurb. Great experience, and so chuffed with the outcome.

Jake and Liam came to build a supporting wall in my garden, unfortunately for them, during the hottest May bank holiday on record. However, despite it being a million degrees, they never complained, slowed down or made a mistake. The wall looks amazing. Thoroughly recommend.

I wanted to replace an old brick wall in my front garden with railway sleepers. I had some idea on how I wanted it to look, but I was very undecided: vertical, horizontal, staggered or squared?. When James came around he made clear suggestions on how make it look nice, simple and within budget. He explained to me what the work involved and showed me some pictures of a previous job he had done so I had a clearer idea. I had to go out the day he came to do the job but he made sure we both were on the same page and he would meet my expectations, and I wasn't disappointed when I came back home. I contacted him afterwards to check details about the look and maintenance of the sleepers and he always replied promptly. I would definitively recommend James.

Groundwork & Foundations- 22 May 2026
John did a fantastic job with the groundworks for our new 150sqm block driveway. He priced keenly, started quickly and was on-site consistently every day for the week. Really skilled with the digger, good at dealing with the neighbours and always fun to talk to. Some aspects of the job changed based on what the dig uncovered, but he was pragmatic and ultimately left me feeling that he just really wanted to do a good job as if it was his own. Highly recommended - 10/10.
